  • When scouring and contraction finishing at $90^{\circ}C$ using Relaxer or Rotary Washer contraction and weight loss ratio in warp and weft directions were excellent. Also surface state of fabric after drying or sanding treatment was excellent without crease. Low melting polyester fabric showed a complete melting bond by heat setting(P/S) at above $160^{\circ}C$. The alkali hydrolysis reaction of polyester showed the breakpoint in the weight loss behavior test, polyester yarn showed a breakpoint ranging from 25% to 28%. This is due to the difference of the hydrolysis rate between regular polyester and soluble polyester. Initially the soluble polyester was eluted and micro-fibrillized 5 times faster than a regular polyester. At a later time, a regular polyester was reduced weight to impart a proper flexibility and drape property to the fabric. As a result of surface sanding finishing, the surface of interior fabric showed a surface state most stabilized when using Mesh No. 220 in mono 0.2d after elution finishing. When the rotation direction of sanding roller was pro-, pro-, pro-, and retro-direction, a directional effect of tuft was not shown, a writing effect as suede was exhibited and a surface state was even. Sublimation fastness was 3-4 class for polyester and 2-4 class for nylon. Light fastness 3-4 class after lapse of 100 hours and 2-4 class after lapse of 160 hours. Abrasion fastness was 3-4 class on wet and 4-5 class on dry Laundry fastness was 2-4 class. As such, the abrasion fastness is slightly reduced upon wetting and the use thereof for interior is excellent, whereas laundry fastness is slightly lowered.

  • This paper suggests the optimal conditions for the laundry to prevent from the electrostatic charge by the evaluation of the electrostatic characteristics in the full process of washing and drying. Cotton, nylon, and polyester fabrics were used as test washing specimens. Detergent and softener were used under the standard washing cycle, and then the electrostatic characteristics of laundry were measured. The results showed that the moisture regain decreased and the electrostatic charge increased with the drying time. It was observed that the specimen fabrics were already dried up before the standard drying cycle was finished. Consequently, the excessive drying caused a generation of electrostatic charge due to the removal of the trace of moisture remaining and the excessive friction. Especially, the softener played an important role to prevent from a generation of electrostatic charge, whose insertion was more effective in the drying than in the rinsing process. It was also shown that the electrostatic charge could be decreased by drying the fabrics of one kind. On the other hand, for drying the mixed kinds of fabrics, the electrostatic charge increased remarkably. Therefore we suggest that the laundry be classified according to the kinds of fiber, and then be washed and dried before excessive drying to reduce electrostatic charge And further, a proper use of softener is effective to reduce electrostatic charge.

  • For a large-scale semiconductor manufacturing clean room, the energy consumed in an outdoor air conditioning system to heat, humidify, cool and dehumidify incoming outdoor air is very large. In particular, the energy requirement to humidify outdoor air in the winter season is generally known to be high. Recently, in order to overcome the high energy consumption nature of a steam generator in a conventional steam humidification type outdoor air conditioning system, an air washer is often introduced instead of the steam generator in the outdoor air conditioning system, which can be called a water spray humidification type outdoor air conditioning system. Therefore, the assessment and comparison of the annual energy consumed in the steam humidification type and the water spray humidification type outdoor air conditioning systems deserves to be examined in order to reduce the outdoor air conditioning load of a clean room. In the present study, a numerical analysis was conducted to obtain the annual electric power consumption of the two outdoor air conditioning systems. It was shown from the comparison of the numerical results that the water spray humidification type outdoor air conditioning system can reduce about 30% of annual electric power consumption of the steam humidification type outdoor air conditioning system.

  • This study examines the character of "Tencel" named as Ecology Fiber and investigates the fitness of it as the textile and the satisfaction in dress when its fastness is compared with that of Rayon classified into Celulose textile. Dye experiment selected 100% Tencel, Rayon for the samples, which were dyed into the direct dye and Turky Blue and Blue of the rective dye and were washed twelve times by the automatic washer. After that, the dye experiment examines the light, laundering, perspiration, rubbing and the composite fastness of the perspiration and hight in the lists of the dye fastness. The results are as follows: 1. The experiment of the color fastness, especially in T-blue of the direct dyestuff, requiring the twelve times-repeatedly-washing by the detergent says that the color fastness of Tencel is superior to that of the cellulose textile ; Rayon. 2. The experiment of the light fastness says that the fastness of Tencel is superior to that of Rayon. 3. The experiment of the laundering fastness says that all of Tencel, Rayon shows the excellent result in the direct dye than in the reactive dye. 4. The experiment of the rubbing fastness says that although Tencel, Rayon show the remarkable result in the desiccant experiment than in the humid one, the rubbing fastness of Tencel is superior to that of others. 5. The experiment of perspiration fastness says that Tencel, Rayon have the closely tightened tendency not to be altered through the acid and alkali perspirations. 6. The experiment of the composite fastness of perspiration and light indicates that the artifical perspirations, though the light lets the fastness of textiles weeken, do very slightly make them loosen, which does not offer the outstanding result. This whole result show that the fastness of Tencel is superior to that of Rayon. The Korean Fiber Enterprise in clothing should make the new and ecological fiber "Tencel" by means of the large amount of investment, and the technique of handing and controlling about it, considering that the dangerous needle of environmental pollution has been slackening the close-related ecological knots of the global environment. global environment.

  • The article aims to making a comparison between traditional Korean and Western furniture metal handles to give the detail information of the handle terms by analyzing the related literature including internet and interviews. In terms of that, the Korean and Western metal handles are compared in the types, components, materials, methods, and terms affecting the development made by the craftsmen before the Industrial Revolution about the mid or late 18th century. As a result, first, ring and drop pull handles were mostly and wooden knobs were a little used to open the furniture doors and drawers. The Korean drop pulls, Deulswae, came out after the ring pulls, Gori, while the Western drops called loop or bail handles as well, came out before the ring pulls. Second, the components were composed by ring, Gori, loop or bail, Deulswae, Post, Baemok, washer, Baemokbatchim, and backplate, Deulswaebatchim. Most of the Western handles were fastened by the bolt and nut, while the post of two strips, Baemok, fastened the Korean metal handles. Third, the metal handles were created of brass and iron mostly, gilded gold and silver. Forth, the method were largely used by casting, engraving, forging, plating, and hammering in the Korean handles, and by casting, molding, engraving, and stamped in the Western handles. Finally, the terms such as "knobs, pulls, drops, ring and drop pulls, loop or bail handles, posts, washers, backplate, casting, molding, engraving, forging, plating, and stamped" were clarified by the two comparison in Korean and English.

  • 우리나라는 1995년 이동전화 가입자수가 백만명, 1998년 천만명을 돌파하고 비약적으로 증가하여 현재 우리나라는 인구대비 이동통신단말기의 보급률이 110%를 넘어섰다. 현재는 어린이나 학생 등 비경제 활동 인구들까지 이동통신 단말기를 사용하고 있다. 명백히 필수재가 된 이동통신 단말기는 그 보급대수가 냉장고, 세탁기, 진공청소기, 승용차를 추월하고 있다. 그런데 이동통신의 생활화는 우리의 생활을 편리하게 하며 이동통신 단말기는 아주 중요한 필수재로 자리매김하였으나 단말기 대금을 비롯한 통신관련 비용은 가계의 큰 부담이 되고 있다. 그런데 공정한 경쟁을 통하여 소비자 후생 나아가 사회적 후생을 최대화 할 수 있도록 시장의 실패를 방지해야할 정부는 적시에 적절한 역할을 하지 못하고 있는 것으로 보인다. 이는 주인-대리인(principal-agent)관점에서도 이해될 수 있을 것이다. 이동통신전화가 상용화된 1990년대 초부터 현재까지의 이동통신정책중 이동통신망의 공동이용, 번호이동, 단말기 유통과 이통서비스의 분리, 망중립성 확보는 주인-대리인문제와 관련한 문제점들을 노정하고 있다.

  • The purpose of this research is to improve sustainable clothes care by comparing household washer's standard course and quick course. Detergency at each course was classified by laundry weight, detergent concentration, and soils. Also, fabric damage from each course was compared. Washing experiments were carried out using two types of washing machines and three types of detergents. Using the standard soiled fabrics of EMPA 108 set, detergency was compared by laundry weight, soil, and detergent concentration. Additionally, fabric damage was evaluated using the mechanical action of MA-40. The results of the research were as follows. First, a standard course, having more working time exhibited better detergency than a quick course. However, the detergency deviation under 6kg laundry weight was as low as 9.0%. Second, detergency by the type of soil was more effective in standard course than in a quick course, but hydrophilic protein soils had a small detergency deviation at 7.6%. Moreover, hydrophobic oil, complex, and particulate soils had a higher deviation at 19.7% Third, fabric damage was in proportion to operating time. Fourth, a quick course showed approximately 80% detergency regardless of the type of detergent. in the case of using 50% of the recommended allowance by the detergent manufacturer. In conclusion, reducing the operating washing time and detergent concentration is in accordance with increasing sustainability, in the case of washing with lightly soiled fabrics under 6kg of laundry weight.

  • 본 연구는 강산성차아염소산수(SAHW)와 초음파(UW)를 병용한 조미오징어 반가공품의 미생물 오염도 저감 기술을 개발하고자 수행되었다. SAHW의 유효염소농도는 $69.67{\pm}0.58ppm$, ORP는 $1071.33{\pm}4.16mV$, pH는 $2.79{\pm}0.05$이었다. 오징어 반가공품을 중량대비 20배의 SHS에 120분간 침지하였을 때 일반세균은 1.49 log CFU/g, 황색포도상구균은 1.32 log CFU/g 감소하였으며, 대장균은 검출한계 이하로 감소하였다. 오징어 반가공품 중량대비 10배의 SAHW에 120분간 침지한 경우, 일반세균은 2.69 log CFU/g, 황색포도상구균은 1.74 log CFU/g 감소하였으며, 20배의 SAHW에 120분간 침지한 경우, 일반세균은 3.62 log lCFU/g, 황색포도상구균은 3.22 log CFU/g 감소하였으며, 대장균은 검출되지 않아 SAHW가 같은 유효염소농도의 SHS보다 살균력이 높은 것을 알 수 있었다. SAHW 단독 처리만으로는 만족할 만한 미생물 저감효과를 얻을 수 없었기에 조미오징어 반가공품을 SAEW에 1차 침지 처리한 후, SAHW에 2차 침지 처리한 결과, 오징어 반가공품 중량 대비 20배의 SAEW로 60분 처리한 후, SAHW로 처리하였을 때는 중량대비 10배, 120분 처리, 중량대비 20배, 90분 처리로 일반세균수는 약 4.0 log CFU/g, 황색포도상구균은 규제치(log 2.0 CFU/g 이하) 이하로 감소하였으며 대장균은 검출되지 않았다. 초음파 세정기에 오징어 반가공품과 중량대비 20배의 TW, SHS, SAHW를 각각 넣어 UW 처리한 후 미생물 오염도를 조사한 결과, SAHW로 60분간 처리하였을 때 일반세균은 검출한계(< 1.00 log CFU/g) 이하로 감소하였으며 황색포도상구균은 규제치 이하로 감소하여 가장 좋은 저감효과를 나타내었다. 대장균의 경우, SAHW 10분간 처리로도 검출한계 이하로 감소하여 SAHW와 UW의 병용이 조미오징어 반가공품 미생물 저감화에 가장 효과가 좋은 것을 알 수 있었다.
